Question

Transcribed Image Text:The figure below shows the soil profile at a construction project site. A soil sample was obtained from location B (depth = 19.0m). A consolidation test was performed on the soil sample. The idealized e-log o' plot from the consolidation test is shown on the right-hand side. The current vertical effective stress, o' z0 =198kPa. (1) y = 18.3 kN/m 2.0m I4.0 A 7.0 m Y = 19.0 kN/m3 Stiff Silty Clay (CL) - C. 10.0 18.0 m y = 19.5 kN/m3 log o' Very Stiff Clay (CL) Point o' (kPa) e A 510 0.38 44 2100 Glacial Till 320 0.31 Fill in the blanks with appropriate answers: Pre-consolidation stress at sample depth (kPa) = No decimals needed Based on the o'z0 value provided, determine if the "Very Stiff Clay" is Normally-Consolidated or Over-Consolidated. "Very Stiff Clay" is Fill in NC or OC. Over-consolidation margin (kPa) = No decimals needed (Show work in hand-calc sheet) %3D Re-compression Index = Report to 3 decimals (Show work in hand-calc sheet)
